If one wishes to form an idea of all those gigantic proportions which, taken as a whole, constitute the ship of the line, one has only to enter one of the six-story covered construction stocks, in the ports of Brest or Toulon. The vessels in process of construction are under a bell-glass there, as it were. This colossal beam is a yard; that great column of wood which stretches out on the earth as far as the eye can reach is the mainmast. Taking it from its root in the stocks to its tip in the clouds, it is sixty fathoms long, and its diameter at its base is three feet. The English mainmast rises to a height of two hundred and seventeen feet above the waterline. The navy of our fathers employed cables, ours employs chains. The simple pile of chains on a ship of a hundred guns is four feet high, twenty feet in breadth, and eight feet in depth. And how much wood is required to make this ship? Three thousand cubic metres. It is a floating forest.
